Abstract

To identify system vulnerabilities, pen testing is essential for cybersecurity. Phases of preparation, reconnaissance, scanning, exploitation, and reporting are all involved. Every phase makes use of tools such as Nmap, Nessus, and Metasploit. To guarantee system, network, and data security, businesses should conduct pen tests regularly using skilled testers. This chapter delves into this important domain of cybersecurity as well as information technology industries. The chapter also discusses ethical issues and various challenges associated with it.
